Unable to Map A Network Drive to Windows Vista Machine????

I have a small wireless network where the other computers are using Windows XP.  I've added a new Windows Vista Home Premium Laptop to this network and I'm having a problem trying to map a network drive over to this machine.  From any of the other machines I can see this new laptop on the network but once I map the drive and try to access it the following message will appear:

Z:\ is not accessible.   Access is denied.  

It still shows on the list of mapped drives.

From the new laptop I can successfully map a drive to any of the other machines on the network.  In other words I can map out from this machine but I cannot map into this machine from another workstation on the network.  I sure this has to be something real simple that I'm missing because I'm new to Vista.

Any help will be appreciated.

Thanks,

ET

I assume you have created the share on the Vista machine. Try disabling the Vista firewall as a test. If that works you can re-configure it to allow access. Firewall can be disabled in: control panel | Windows Firewall | Turn on or off Windows firewall.

Thanks RobWill ...

Yes, I've disabled Windows Firewall on all three machines on the network.  It's just real strange in that I can map from the Vista machine but cannot map to it from any of the other machines on the network.  Something in Vista is blocking the incomming mapping but I just can't seem to find where.

It should only need to be Vista, the PC accepting the incoming connection. that needs the firewall modified or disabled.

I Haven't worked with Vista Home but I assume it is similar to Pro. Have you enabled "file sharing" and "Network Discovery"? There are located in control panel under "Network and Sharing Center".

Yes, everything is turned on except "Password protected sharing".

I just turned off all the Firewalls to see if that would make a difference.  It's got to be some setting in Vista becaue even when I view all computers on the network (from the Vista machine) and select (double click) one of the other XP wireless laptops I will get the message ...

\\Inspiron1 is not accessible.  You might not have permission to use this network resource.....  Access denied.

But I can right-click Network and manually map a drive over to this computer by entering ....

Z:
\\Inspiron1\C

From Inspiron1 I will get Access denied each time I try to map over to the Vista machine each time.

May be best to run through the following as there are quite a few changes with Vista such as Network Discovery, Network Location Type, different default workgroup names and so on.

Thanks RobWill ...

I've probably been through every step in that article about 4 or 5 times in the last few days.  It's just another one of those simple basic things (like connecting 3 laptops all in 8 ft of each other) that M/S makes very, very, very complicated and no one, no matter how much time you spend reasearching and changing settings can make it work.  Take a lap-link cable and string the units together in 10 minute!!!!

The article is a good summary and may be beneficial somewhere down the road.

Given the fact that I can map from the Vista machine into the other XP machines but not the other way indicates that Vista is blocking the incomming connection.  From the article it probably has something to do with the user accounts and how they are setup on XP and how they are setup in Vista.  I'm not using passwords in XP or Vista so that may have something to do with it.

Thanks anyway ...

Passwords are a requirement for file sharing. It's not supposed to work with even XP unless you do some tweaking. Try using a matching username and password on both machines. They have to be exactly the same and not blank. This also eliminated the need to authenticate when you connect to a remote PC as you have already done so at logon, and the credentials are carried forward to the next connection.

Can you see the Vista PC in network places from the XP machine? If not it should be related to firewall or "Network Discovery ". If you can see the PC but not connect to a sher the share has not been created properly or authentication is incorrect, either wrong user name, or blank or no password.

Vista and Server 2003 employ tighter security, so I doubt Vista will work without the password. I haven't used Vista in a workgroup (only domains) but you usually need to use the username in the form of domain\username, so in a workgroup you may need computername\username.

"Access denied" is usually related to failed authentication.
"path not found" or similar would be more likely for blocked by firewall or configuration.

Yes, I can see the Vista PC from the XP machine (My Network Places).

>>>>If you can see the PC but not connect to a share the share has not been created properly or authentication is incorrect, either wrong user name, or blank or no password.<<<<<

I also think that's the problem but every possible configuration I've tried has failed.

Same user, same workgroup and same password on both machines (XP and Vista)  and I still get Access Denied when I try to map from the Access machine to the Vista laptop.  

I'm starting to believe maybe it's not supposed to do that given Vista has tighter security as there is a Public on HP9640 (Hp9640) which is the vista machine that shows up in My Network Places on the  XP machines.   I've reviewed that folder on the Vista machine and its sharing properties are no different that what I've been using to try and share C:

Does the "Public on HP9640 " share work?

At a command line, on the Vista machine run:
  net share
Is the share listed?

Wonder if Vista let's you share the C: drive. That has always been considered a security risk. There is a default administrator  C$
Perhaps try creating a shared folder rather than the entire C: drive, if you haven't.

Have a look at Lee's comments in the following link and the link with-in that he provided to a previous question.

Yes, the share works in that I can click on any folders/files without getting an access denied error message.

Net Share shows the following Share Names:

ADMIN$
print$
C$
IPC$
D$
E$
C
D
Public
Users

>>>>>Perhaps try creating a shared folder rather than the entire C: drive, if you haven't.<<<<<<

How???

Vista and XP home use simple file sharing so I am not that familiar with it, but should be as simple as right click on any folder (don't use a system folder, i.e Windows) choose the sharing tab option, and check the box "share this folder" (may have to click advanced), then click permissions, and as a test enable the 3 boxed to give "everyone" full control. So long as you are connecting with a legitimate user account you should be able to access.

I assume
C & D above are shares you created?
C$ is a built in default share for administrator use.

Ok, sorry I misunderstood your original comments.  I was thinking you wanted to create a folder to rename C:.

Yes, I can share a Folder on the Vista machine something like C:\DB_Development and it shows up like "DB_Development on HP9640".
I can access this folder without getting the Access Denied error message from My Network Places on the XP Machine.

I guess this means I will not be able to just do a Map Z: over to the root on the C: drive of the Vista Machine.  I should share the individual folders then use the UNC name rather than a mapped drive letter.  In this case "\\HP9640\DB_Development\MyFile.mdb".

Kind of makes sense now give how Vista has different security features.

Much appreciated RobWill ....

As mentioned above,  mapping from the XP machine into the Vista PC the folder needs to be shared.  I was trying to map a drive letter to the root on C: for the Vista machine and looks like that will not be possible due to Vista's tightened security.  As long as I know how it works I can flow with that.

Thanks,

Sorry ET, I stepped away for a while.
Sounds like you are doing everything right so it must be a security feature with the C: drive. I just tried it with Vista Enterprise and had no problem connecting from an XP machine, but it was a domain admin. The concern is if you share the C: drive the remote user could conceivably delete or alter your System files in the Windows directory.
You should however be able to share the D: drive, and this is quite common. i.e. the shares are on a different partition. Sounds like I need to work with Vista home a bit.

Thanks, and hope you are satisfied with your findings.
Cheers !
